Carbon offsets via forest protection [REDD] are mostly myth

REDD-Monitor : "It is entirely untrue that all 13 of the projects have stable tenure over forest lands. Several of the communities have entirely collapsed with no practical management over forest lands. 15 year agreements with the Forestry Administration which can be revoked at any time, and which in practice have been entirely undermined by the presence of the Royal Cambodian Armed Forces in no way constitutes secure tenure. There are now entire villages located within core project forests which community members have been powerless to stop. A large tract of the largest community forest area is also to be submerged by a Chinese built dam, yet the temporary forest agreements were ignored."

Using methane hydrate for fuel a deadly mistake

BBC News: "Quite apart from reaching them at the bottom of deep ocean shelves, not to mention operating at low temperatures and extremely high pressure, there is the potentially serious issue of destabilising the seabed, which can lead to submarine landslides.

A greater potential threat is methane escape. Extracting the gas from a localised area of hydrates does not present too many difficulties, but preventing the breakdown of hydrates and subsequent release of methane in surrounding structures is more difficult.

And escaping methane has serious consequences for global warming - recent studies suggest the gas is 30 times more damaging than CO2."
